Description

Horizontal member coupled non-welded modular structure

According to the present invention, a modular unit is manufactured by combining a horizontal connector positioned at the end of a horizontal member with a joint coupled to the end of a vertical member, so that rapid and precise fabrication is possible by minimizing the welding process. It is about a horizontal member coupling type non-welding modular structure that can easily combine modular units by mutually coupling them.

In an apartment building, the floor plan of each household is kept the same, so it is often repeated for each floor by a large formwork such as a gang form. On the other hand, the roof floor is different from that of the lower generation, so it is impossible to construct it using a large formwork, and it is often constructed after dismantling the tower crane.

However, this conventional method is difficult to secure quality, and due to the nature of the roof floor being constructed at the time of the completion of the frame construction, there are restrictions on the supply of on-site manpower and the use of equipment such as tower cranes, making construction difficult and delaying the construction period.

Accordingly, the demand for modular systems for the construction of rooftop structures has recently increased.

The modular system is a construction system that completes the structure by stacking and assembling modular units pre-fabricated in a box shape at the factory in a vertical, horizontal, and vertical direction, unlike existing buildings where frame construction is performed on site.

Such a modular system has the advantage of being able to secure excellent quality and greatly shorten the construction period because most of the processes such as various interior materials, mechanical equipment, and electrical wiring are performed in factories as well as frames.

The modular unit constituting the modular system is usually made of a hexahedron, and a vertical member is provided at each corner, and the upper and lower ends of the vertical member are connected by an upper horizontal member and a lower horizontal member, respectively.

In the conventional modular unit, a vertical member and a horizontal member are mainly joined by welding during factory production.

However, in this case, there is a risk of quality deterioration, productivity is reduced, and there is a limit to automated production. In addition, since each member must be cut during welding and dismantling, the dismantling operation is cumbersome, and there is a difficulty in recycling the material. In addition, if a length error occurred when cutting a member, it was difficult to correct.

In addition, in the existing modular structure, there were many cases in which pillar members were interconnected when connecting upper and lower modular units (Patent No. 10-0923637, etc.). However, since the pillar member generally uses a closed cross-sectional member such as a square tube, a separate bonding member for cutting or bonding the pillar member is required for assembling the upper and lower modular units. In addition, there was a problem in that the workability was inferior because the joining work had to be done inside the cross-section of the column member.

On the other hand, since the modular unit, which is usually made of steel, must have a fire resistant structure to be used as a main structural part, a fire resistant spraying treatment must be performed on the outside of the steel material.

At this time, since on-site fire-resistance spraying involves many difficulties, it is advantageous to perform fire-resistance spraying in advance at the time of factory production of the modular unit.

Conventional modular units may use a separate bonding member for bonding between modular units, such as the bracket of Korean Patent Registration No. 10-1672469. However, in this case, fire-resistance spraying was not possible on the joint member or the part to which the joint member was joined, so fire-resistance spraying was performed later after on-site joining.

Therefore, when spraying refractory materials for refractory coatings, the working environment is deteriorated due to scattering of refractories, and there is a risk of worker safety issues as the spraying operation is carried out at high altitude with the modular unit installed. There is a problem in that the refractory material falls off.

In order to solve the above problems, the present invention aims to provide a horizontal member-coupled non-welded modular structure that can be manufactured quickly and precisely by minimizing a welding process.

An upper horizontal member (6a) and a lower horizontal member (6b) provided between the joint (3b), respectively; The lower modular unit 1 and the upper modular unit 1' are mutually coupled to the upper horizontal connector 5a of the lower modular unit 1 and the lower horizontal connector 5b of the upper modular unit 1' It is characterized in that it is fixed.

The present invention enables rapid and precise fabrication by minimizing the welding process, does not require on-site construction for fireproof coating, and by interconnecting horizontal members (6a, 6b) instead of vertical members (2), modular units (1) in the field , 1') is to provide a modular structure that can be easily combined with a horizontal member coupling type non-welding.

The modular structure of the present invention is applicable not only to the rooftop structure but also to various buildings such as living houses, school facilities, various accommodation facilities, officetels, and temporary disaster facilities.

The modular structure of the present invention is configured by stacking a plurality of modular units (1, 1') up and down.

Each modular unit (1, 1') has a vertical member (2) provided to be spaced apart from each other at the four corners; an upper joint (3a) and a lower joint (3b) respectively coupled to the upper end and lower end of the vertical member (2); and horizontal connectors 5a and 5b provided at both ends of the girder body 4 and the girder body 4, one side of which is coupled to the joint holes 3a and 3b, and adjacent upper joint portions 3a and lower portions. An upper horizontal member (6a) and a lower horizontal member (6b) provided between the joint (3b), respectively; is composed of

The upper joint 3a and the lower joint 3b are perpendicular to each other to connect the four vertical members 2 and the upper and lower horizontal members 6a and 6b connecting the upper and lower parts of the adjacent vertical members 2 to each other. It is coupled to the upper end and the lower end of the member (2), respectively.

The upper horizontal member (6a) is coupled between the upper joint (3a) coupled to the upper end of the adjacent vertical member (2). And the lower horizontal member (6b) is coupled between the lower joint (3b) coupled to the lower end of the adjacent vertical member (2).

The upper and lower horizontal members (6a, 6b) are not directly coupled to the vertical member (2), but are coupled by separately manufactured joint (3a, 3b) and horizontal connector (5a, 5b).

Therefore, the vertical member 2 and the horizontal member 6a, 6b do not need a separate configuration for bonding, and can be freely cut to an appropriate length according to the size of the modular units 1 and 1'. At this time, it is economical to use a generally used ready-made section steel.

The second coupling bolt (9b) may be configured as a one-way bolt to be fastened at the upper portion of the upper joint (3a) or the lower portion of the lower joint (3b).

Since the upper junction 3a and the lower junction 3b can be configured vertically symmetrically, they can be manufactured in one standard. That is, the joint parts 3a and 3b of the same shape can be used for both the upper joint part 3a and the lower joint part 3b.

Accordingly, material production and management efficiency can be greatly improved.

As shown in FIG. 4 , a core 30 may be formed between the engaging grooves 31 formed on each side of the joint 3a and 3b. The inside of the core 30 may be formed to be hollow to reduce the amount and weight of steel.

At this time, the vertical member 2 is composed of a hollow steel pipe.

That is, the outside of the joint (3a, 3b) is formed in a cross-sectional shape corresponding to the outside of the vertical member (2), the outside of the vertical member coupling portion 38 is a cross section corresponding to the inside of the vertical member (2) By forming in a shape, it can be configured so that there is no part protruding to the outside when the joint (3a, 3b) and the vertical member (2) are coupled.

In a state in which the vertical member coupling part 38 is inserted into the vertical member 2, the third coupling bolt 9c is fastened from the outside of the vertical member 2 to the vertical member 2 and the vertical member coupling part ( 38) can be mutually fixed.

A groove into which the head of the third coupling bolt 9c is inserted may be formed in the bolt hole H formed in the vertical member 2 so that the third coupling bolt 9c does not protrude to the outside.

The third coupling bolt 9c may also be configured as a one-way bolt.

Fig. 16 is a perspective view showing the horizontal connector, and Fig. 17 is a perspective view showing the coupling state of the horizontal connector and the girder body.

16 and 17, the vertical girder body 4 is a C-shaped steel in which the inner side of the modular units 1 and 1' is opened, and the other side of the horizontal connector 5a, 5b is the girder body. (4) is inserted into the inner side of the girder body 4, the upper and lower surfaces of the upper and lower flanges of the upper and lower flanges of the upper and lower flanges are respectively in close contact with each other fixed girder connection 53 can be formed to protrude.

The girder body 4 preferably uses a C-shaped steel having an open cross-section to facilitate bonding with the horizontal connectors 5a and 5b.

In this case, in order to couple the girder body 4 with the horizontal connectors 5a and 5b, a girder connection part 53 of a shape corresponding to the inner surface of the girder body 4 is protruded from one side of the horizontal connectors 5a and 5b. can be formed

The girder connection part 53 may be formed in a U-shaped cross section so that the upper wall 531 and the lower wall 532 are connected by the side wall 533 .

The upper wall 531 and the lower wall 532 of the girder connection part 53 may be respectively fixed to the upper flange and the lower flange of the girder body 4 by a fourth coupling bolt 9d.

A guide that is formed long in the longitudinal direction of the girder body 4 around the bolt hole H on the inner surfaces of the upper wall 531 and the lower wall 532 so that the washer moves only in the longitudinal direction and does not flow from side to side A groove G may be formed.

In general, ready-made C-beams are formed so that the inner surface of the upper and lower flanges is inclined.

Therefore, the upper wall 531 and the lower wall 532 of the girder connection part 53 are also preferably formed to be inclined to correspond to the inclination of the inner surface of the upper and lower flanges of the girder body 4, which is a C-shaped steel.

Since the horizontal connectors 5a and 5b can be formed of a cast steel product, it is easy to manufacture in a shape corresponding to the inner circumferential surface of the girder body 4 .
